Some folks in my guild were having a conversation about how the game decides who gets loot from an open world target and we need some clarification. I've read that if you do at least 3% of the targets health in damage you will get loot, or if you are a healer and heal a target that does that amount of damage you will get loot.
Can anyone clear up the rules of who gets loot when a group attacks an open world target? Lets use an Imperial City "boss" mob for an example and a group of 12 attacking it.
